<h1>Real Op-Amps</h1>
The ideal op-amp element uses an ideal approximation to op-amp behavior.  It has infinite <a href="javascript:nw.Shell.openExternal('https://en.wikipedia.org/wiki/Slew_rate');">slew rate</a>
and output current.
<p>
The real op-amp element uses a subcircuit to emulate a real op-amp implementation with finite slew rate and output current.  Presently,
the two implementation options are LM741 and LM324.
<p>
You can also modify the slew rate or output current, which will modify the circuit to change these values from the default.
<p>
These subcircuits are complicated, so you may run problems with convergence, especially if you increase the slew rate.  Try decreasing
the time step size if this happens.
<p>
The LM324 can act very glitchy as well if the slew rate is increased.  Decreasing the time step size proportionately should fix this.
